Hello everyone,
i' m studying how to implement Queue Sharing Group..so i have defined the following environment on Zos.
I have 2 LPAR in Sysplex (Lpar1 and Lpar2)
I have defined on Lpar1 ...1 Mq (mq1) and 1 cics (cics1).
On Lpar2 i have defined 1 mq (mq2).
Mq1 and Mq2 belong to a queue sharing group called Mqgt.
At last i have defined a shared queue (A) on Mqgt...triggered by cics1.
Now 2 example.
Example 1
I have Mq1 on...cics1 on....and mq2 on.
If i put a message on A ...cics1 let start a transaction that get the message.
Example 2.
I have cics1 on...mq2 on...but mq1 down.
If i put a message on A....cics1 doesn't let start the transaction.
It's correct this test?
Transaction start only if a cics is started on the same Lpar where Mq is started?
Thank u for your help |

Are you reading any IBM documentation about this? Are you following documented instructions?

Are mq1 and mq2 qiueues? Or qmgrs? Or qsg's?

Uh, ok.

What exactly does 'down' mean?

What do you see that leads you to believe that cics1 doesn't let the transaction start? An error message of some kind? What exactly?

I'd suspect that the message stayed in a local queue, and did not get put to the shared queue.
Is the queue really shared in the qsg?

Hello bruce..
i have followed ibm documentation to do that.
Mq1 and mq2 are 2 queue manager belonging to queue sharing group called mqgt.
down mean...not started.
In the example2...when i put message on queue...cics1 does do nothing...while in example 1 ...it let start transaction.
message are on a queue local with disposition shared...as u can see from ISPF table
Type action codes, then press Enter. Press F11 to display queue status.
1=Display 2=Define like 3=Alter 4=Manage
Name Type Disposition
<> * QUEUE SHARED MQGT
PROVA QLOCAL SHARED |

About your question : 'Transaction start only if a cics is started on the same Lpar where Mq is started? '
Response: Yes. CICS must be connect to a Queue Manager . Both should be running in the same LPAR. In your test , if MQ1 is down , you should start CICS1 on LPAR2.

Please be precise. Are the messages on the LOCAL queue? Or on the shared queue?

This is maybe a triggering issue not properly set up on mq2 ?!?

ah okay, i assumed (wrongly) that you start cics1 on lpar2 to work together with mq2.
but you leave cics1 on lpar1 with mq1 down. well..... cics must be "local" to mq. so either start cics1 on lpar2, or have cics2 for lpar2 / mq2 when mq1 is down.

Ok..it's what i wanted to know.
So, in my environment...where we have no Cicsplex between Lpar1 and Lpar2...having QSG give us no effort..because i have to start cics in the LPAR where Queue Manager works...
For ex,
if on Lpar1 i have cics1 and Mq1...while on Lpar2 i have Mq2 without cics...if Mq1 go stopped for some reason...i have to start cics1 on Lpar2...
Thank u all..u |

Hi, we already have sysplex in place, but we are not using it. the second broker that is designated for sysplex is kept down.
Before we start using it, I want a list of items that are required to enable it. could someone help with it? Thanks. |

Is your system Parallel Sysplex?
Do you have a CF?
Have you (or someone else) created the CF structures?
Do you have the DB2 Data Sharing layer of software installed?
I ask these questions because these are prerequisites for WMQ for z/OS shared queues.
